Personal Maid's Secret is a 1935 American comedy film directed by Arthur Greville Collins and written by Lillie Hayward and F. Hugh Herbert.
The film stars Margaret Lindsay, Warren Hull, Anita Louise, Ruth Donnelly, Arthur Treacher and Frank Albertson.
Lizzie repeatedly persuades Joan to upgrade her family's lifestyle so they can mingle with the elite and Jimmy can make valuable business contacts.
Meanwhile, Joan's inventor brother, Kent Fletcher, meets and falls in love with Diana Abercrombie, newly returned from a European finishing school.
When he was killed, Lizzie agreed to let his wealthy parents raise Diana as their own, as she, then their upstairs maid, could not provide what they could.
